Oxygen Defect Engineering of Hexagonal Perovskite Oxides to Boost Catalytic Performance for Aerobic Oxidation of Sulfides to Sulfones

Advanced Functional Materials, EarlyView.
Ru‐substituted hexagonal perovskite SrMnO3, featuring face‐shared oxygen species, is designed as an effective heterogeneous catalyst for the aerobic oxidation of sulfides. The catalyst demonstrates high selectivity to sulfones (>99%) under mild reaction conditions (≥30 °C). Ru substitution promotes oxygen vacancy formation of face‐shared oxygen species

The oxygen tightrope [PDF]

Canadian Anaesthetists’ Society Journal, 1966
During anaesthesia and during the management of respiratory failure by intermittent positive pressure ventilation, incipient hypoxaemia is common owing to the frequent occurrence of an increased physiological shunt. This hypoxaemia may be offset by raising the inspired oxygen tension and by hyperventilation.

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Flow‐Induced Vascular Remodeling on‐Chip: Implications for Anti‐VEGF Therapy

Advanced Functional Materials, EarlyView.
Flow‐induced vascular remodeling plays a critical role in network stabilization and function. Using a vasculature‐on‐chip system, this study reveals how physiological VEGF levels and flow affect vascular remodeling and provides insights into tumor vessel normalization.

Nitric oxide delivery into oxygenators of artificial and assisted blood circulation. Current state and prospects of technology development (literature review)

Вестник анестезиологии и реаниматологии
The use of cardiopulmonary bypass (CPB) technologies is often associated with ischemic and re-perfusion injury to the myocardium. The contact of patient’s blood with the surface of the extracorporeal circuit leads to platelets activation and often ...
